Glitch (The Forbidden Realm)

You find yourself trapped in a new universe. Confused, you wonder around and encounter an annoying worm. You also find a shop. With a guy called Bob who sells you random stuff, until your eyes lock on a computer that costs a Memory Card.

You find this green glitching creature. The worm tells you that once you go insane, you start chasing people and become aggressive. Go through the glitching blue orbs to enter a new area. Even to this day I have no clue why the orb does that.
